Description

Technical Field

[0001] This utility model relates to the field of mobile phone component testing equipment technology, and in particular to an optical testing platform. Background Technology

[0002] In the production of mobile phone back panels (BG), to meet high-standard shipment requirements, automated optical inspection (AOI) equipment is typically used for visual inspection. However, without prior optical verification before mass production of AOI equipment, numerous uncertainties will arise during the later use of the AOI equipment, affecting the inspection results.

[0003] In existing technologies, a testing platform needs to be built to meet the requirements for detecting appearance defects on the back panels of mobile phones before mass production of automated optical inspection equipment. However, traditional testing platforms have difficulty simultaneously detecting the appearance features of the front of one mobile phone back panel and the appearance features of the back of another mobile phone back panel, which reduces testing efficiency and may also lead to some defects not being detected in time, affecting the quality of the mobile phone back panels and the production schedule.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] The purpose of this invention is to provide an optical inspection platform that can simultaneously inspect the appearance features of the front of a mobile phone back panel and the appearance features of the back of another mobile phone back panel, thereby improving inspection efficiency, and thus improving the quality of mobile phone back panels and production progress.

[0011] Preferably, the front detection component includes a first detection camera and a first adjustment member. The first detection camera is mounted on the frame via the first adjustment member. The first adjustment member is used to adjust the position and angle of the first detection camera so that the first detection camera is aligned with the features on the front of the back panel of the mobile phone.

[0012] Preferably, multiple first detection cameras are provided, and the number of first adjustment components corresponds to the number of first detection cameras. Each of the multiple first detection cameras corresponds to one of the appearance features on the front of the back panel of the mobile phone.

[0013] Preferably, the optical inspection platform further includes a light-emitting component disposed on the frame, the light-emitting component being used to illuminate the appearance features of the mobile phone back panel fixed by the fixing mechanism.

[0014] Preferably, the light-emitting component includes a main light and a fill light disposed on the frame, the main light being located below the fill light, and both the main light and the fill light facing the fixing mechanism to illuminate the back panel of the mobile phone fixed by the fixing mechanism.

[0019] The beneficial effects of this utility model are:

[0020] This invention uses a fixing mechanism to fix at least two mobile phone back panels with opposite orientations, allowing simultaneous inspection of at least one front-facing mobile phone back panel and at least one back-facing mobile phone back panel. Compared to the traditional single-sided inspection method, this significantly saves operation time. Especially during large-scale inspections, the inspection mechanism does not need to stop and wait for the mobile phone back panels to be flipped, which can significantly increase the number of inspections per unit time. This not only improves inspection efficiency but also avoids the problem of some defects being difficult to detect in a timely manner, thereby improving the quality of mobile phone back panels and production progress.

[0030] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0031] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0032] In this application, the term "and / or" describes a relationship between related objects, indicating that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of only one centrifugal vortex magnetic pump, the simultaneous existence of one centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump, or the existence of only one centrifugal vortex magnetic pump. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0033] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0034] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0035] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0036] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0037] Please see Figures 1 to 3 This embodiment provides an optical inspection platform for detecting the appearance features of the front and back of a mobile phone back panel 100. The optical inspection platform includes a frame 1, a fixing mechanism 2, and a detection mechanism 3. The fixing mechanism 2 is disposed on the frame 1 and configured to fix at least two mobile phone back panels 100 with opposite orientations, that is, at least one front-facing mobile phone back panel 100 and at least one back-facing mobile phone back panel 100. The detection mechanism 3 is disposed on the frame 1 and located above the fixing mechanism 2. The detection mechanism 3 is configured to detect the appearance features of the front of one mobile phone back panel 100 and at least one appearance feature of the back of the mobile phone back panel 100.

[0038] With this configuration, the fixing mechanism 2 can fix at least two mobile phone back panels 100 with opposite orientations, allowing simultaneous inspection of at least one front-facing mobile phone back panel 100 and at least one back-facing mobile phone back panel 100. Compared to the traditional single-sided inspection method, this greatly saves operation time. Especially during large-scale inspections, the inspection mechanism 3 does not need to stop and wait for the mobile phone back panel 100 to be flipped, which can significantly increase the number of inspections per unit time. This not only improves inspection efficiency but also avoids the problem of some defects being difficult to detect in a timely manner, thereby improving the quality of the mobile phone back panel 100 and the production progress.

[0039] Generally speaking, the back panel of a mobile phone has many characteristics in terms of appearance, structure, and performance on both the front and back. For example, the front may have printed patterns, camera holes, etc., while the back may have heat dissipation holes, antenna areas, etc.

[0040] To make the test results more accurate, the testing mechanism 3 includes at least one front detection component 31 and at least one back detection component 32. The front detection component 31 is used to detect the appearance features of the front of the mobile phone back panel 100, and the back detection component 32 is used to detect the appearance features of the back of the mobile phone back panel 100.

[0041] Understandably, based on the different features of the front and back of the mobile phone back panel 100, the front detection component 31 and the back detection component 32 are specially designed to fully cover the appearance features of the front and back of the mobile phone back panel 100, avoid detection omissions, ensure that possible defects or non-compliance with standards can be found on each surface, and help improve the accuracy and reliability of the detection.

[0042] It is also understandable that when testing the back panel 100 of different mobile phone models, the front and back detection components 32 can be upgraded according to actual needs. For example, when the front of the mobile phone back panel 100 adopts a new coating technology, the front detection component 31 can be upgraded separately to adapt to the new detection requirements and improve the adaptability and service life of the equipment.

[0043] Specifically, the front detection component 31 includes a first detection camera 311 and a first adjustment component 312. The first detection camera 311 is mounted on the frame 1 via the first adjustment component 312. The first adjustment component 312 is used to adjust the position and angle of the first detection camera 311 so that the first detection camera 311 is aligned with the features on the front of the mobile phone back panel 100.

[0044] It is worth noting that the appearance features on the front of the mobile phone back panel 100 are distributed in different positions. The position and orientation of the first detection camera 311 can be precisely adjusted by the first adjustment component 312 so that it can accurately focus on each feature that needs to be detected, ensuring that the captured image is clear and complete, thereby improving the accuracy of feature detection and enabling the identification of smaller defects or more subtle size deviations.

[0045] Furthermore, different models of mobile phone back panels 100 may differ in size, shape, and feature distribution. The adjustable first inspection camera 311 can flexibly adapt to these changes, making it suitable for inspecting various specifications of mobile phone back panels 100 by adjusting its position and orientation, without the need to design a fixed inspection mechanism 3 for each mobile phone back panel 100, thus improving the versatility and adaptability of the inspection platform.

[0046] It should be noted that the structure of the first adjusting member 312 can be selected according to the actual application scenario, and this embodiment does not impose specific requirements or limitations on it. For example, the first adjusting member 312 consists of a slide rail and a slider that cooperates with it. The slide rail is fixed on the frame 1, and the slider can slide freely on the slide rail. The first detection camera 311 is mounted on the slider, so that by manually pushing the slider, the position of the first detection camera 311 in the slide rail direction can be adjusted, which facilitates adjusting the distance between the first detection camera 311 and the back panel 100 of the mobile phone to achieve the optimal shooting position. In addition, the angle corresponding to the first detection camera 311 can be composed of multiple rotatable joints and connecting shafts, which can adjust the angle in multiple directions. The operator can manually rotate each joint of the universal joint to flexibly adjust the orientation of the first detection camera 311, so that it can be aligned with the features on the front of the back panel 100 of the mobile phone from different angles to meet different detection needs.

[0047] Specifically, multiple first detection cameras 311 are provided, and the number of first adjustment members 312 corresponds to the number of first detection cameras 311. The multiple first detection cameras 311 correspond one-to-one with the appearance features of the front of the mobile phone back panel 100.

[0048] With this setup, each first inspection camera 311 is responsible for inspecting a specific feature on the front of the phone back panel 100. Multiple first inspection cameras 311 can work simultaneously, enabling parallel inspection of the phone back panel 100's appearance features. Compared to a single first inspection camera 311 inspecting each feature individually, this significantly shortens the inspection time, improves overall inspection efficiency, and meets the needs of rapid inspection of the phone back panel 100 on large-scale production lines. Because multiple first inspection cameras 311 inspect simultaneously, each first inspection camera 311 only needs to focus on its corresponding feature, eliminating the need to frequently switch inspection positions and parameters between different features. This reduces the time required for adjustment and positioning of the first inspection cameras 311, further shortening the entire inspection process cycle and improving production speed.

[0049] It is worth noting that appropriate lighting can enhance the contrast between features on the back panel 100 and the background. For example, under good lighting conditions, the edges of minor scratches, textures, or markings on the back panel 100 will be clearer and more distinguishable from the surrounding area, making it easier for the detection equipment to identify and analyze them more accurately, thereby improving detection precision and enabling a more accurate determination of whether the features meet the standards.

[0050] Therefore, to further improve detection accuracy, the optical inspection platform also includes a light-emitting component 4 mounted on the frame 1. The light-emitting component 4 illuminates the appearance features of the phone back panel 100 fixed by the fixing mechanism 2. Understandably, the light-emitting component 4, through a reasonable layout and angle design, can uniformly illuminate the phone back panel 100, effectively eliminating shadows caused by the object's shape or the angle of the light source, and avoiding interference from shadows on feature detection. Simultaneously, it can also reduce reflections on the surface of the phone back panel 100, enabling the inspection equipment to obtain more complete and accurate feature information, preventing some features from being undetectable or leading to misjudgments due to reflections.

[0051] In addition, sufficient and uniform lighting can ensure that inspection cameras and other equipment can quickly acquire clear images of the mobile phone back panel 100, reducing the need for multiple shooting and parameter adjustments due to insufficient or uneven lighting, thereby saving inspection time, improving inspection efficiency, and facilitating rapid and continuous inspection on the production line.

[0052] In this embodiment, the light-emitting component 4 includes a main light 41 and a fill light 42 disposed on the frame 1. The main light 41 is located below the fill light 42. Both the main light 41 and the fill light 42 are facing the fixing mechanism 2 to illuminate the mobile phone back panel 100 fixed by the fixing mechanism 2.

[0053] With this configuration, the combination of the main light 41 and the supplementary light 42 can illuminate the back panel 100 of the mobile phone from different positions and angles. The main light 41 provides the main basic illumination, while the supplementary light 42 provides supplementary illumination to areas where the main light 41 may produce uneven illumination. The two work together to effectively reduce dark areas and bright spots on the back panel 100 of the mobile phone, so that the entire surface of the back panel 100 of the mobile phone receives more uniform illumination. This is beneficial to improving the accuracy and consistency of detection and avoiding inaccurate detection of some features due to uneven illumination.

[0054] It should be added that different angles of light illumination can produce different light and shadow effects on the features on the back panel 100 of the mobile phone. When the main light 41 shines from below, it may highlight some macroscopic features on the surface of the back panel 100 of the mobile phone, while when the supplementary light 42 shines from above or other angles, it can illuminate details that the main light 41 may miss, such as some tiny depressions, bumps or textures. Through this multi-angle illumination, the feature details of the back panel 100 of the mobile phone can be displayed more comprehensively, making it easier for the testing equipment to identify and analyze them more accurately.

[0055] Specifically, the main light 41 can form an illumination area centered on the front-facing mobile phone back panel 100, ensuring that the core parts and key features of the mobile phone back panel 100 receive the most sufficient and direct illumination, making their details clearly visible. This facilitates the inspection equipment's accurate capture and analysis of potential minor defects and process flaws in the central area of ​​the back panel, improving the resolution and accuracy of the inspection. Furthermore, forming an illumination area around the center of the mobile phone back panel 100 helps achieve a more uniform illumination distribution. The illumination pattern radiating from the center reduces the difference in illumination intensity between the edge and the center, avoiding situations where the center is too bright or too dark, or the edges are insufficiently illuminated. This ensures that the entire surface of the mobile phone back panel 100 can be inspected under relatively consistent illumination conditions, improving the consistency and reliability of the inspection results.

[0056] In this embodiment, the main light 41 includes two light strips connected end to end, and both light strips face the mobile phone back panel 100 located at their center. Of course, in other embodiments, the main light 41 can also be an arc light strip, as long as the mobile phone back panel 100 is located at the center of the arc, so there are no specific requirements or limitations on this.

[0057] In addition, the orientation of the fill light 42 can be adjusted to accommodate different models of mobile phone back panels 100. In this embodiment, the orientation of the fill light 42 is adjustable. Specifically, the fill light 42 can be installed on the frame 1 using a structure similar to the first adjusting member 312 mentioned above, so it will not be described in detail.

[0058] Different models of mobile phone back panels 100 have varying thicknesses. Therefore, the reverse side detection component 32 includes a second detection camera 321 and a second adjustment component 322. The second detection camera 321 is mounted on the frame 1 via the second adjustment component 322, which is used to adjust the height of the second detection camera 321. By adjusting the height of the second detection camera 321, a suitable distance can be maintained between it and the reverse side of the mobile phone back panel 100, ensuring that the details of the reverse side of the back panel can be clearly captured regardless of changes in the thickness of the back panel 100, thus improving the compatibility of the detection system with different mobile phone back panels 100.

[0059] Furthermore, the reverse side detection component 32 includes an auxiliary light 323, which is mounted on the frame 1 via a second adjusting member 322. The auxiliary light 323 is located directly below the second detection camera 321. The second adjusting member 322 is used to adjust the height of the auxiliary light 323. A clearance hole is provided in the middle of the auxiliary light 323 corresponding to the position of the second detection camera 321. The auxiliary light 323's location directly below the second detection camera 321 and the presence of the clearance hole prevent the auxiliary light 323 from obstructing the camera lens, ensuring that light can evenly illuminate the reverse side of the phone back panel 100, avoiding shadows, and allowing the camera to capture a clear, interference-free image, thus improving detection accuracy. In addition, the adjustable relative position and height of the auxiliary light 323 to the camera help optimize image contrast.

[0060] It should be noted that the structure of the second adjusting component 322 may consist of a slider, a guide rail, and adjusting knobs. The guide rail is vertically fixed to the frame 1. Two sliders are provided, and two adjusting knobs are correspondingly provided. The second detection camera 321 is mounted on one slider, and the auxiliary light 323 is mounted on the other slider. Each adjusting knob is screwed to its corresponding slider and can abut against the guide rail or the frame 1. This embodiment does not impose specific requirements or limitations on the structure of the second adjusting component 322.

[0061] Generally, mobile phone back panels 100 are typically thin, fragile, or irregularly shaped. Using traditional clamps to fix them can easily cause deformation or damage, affecting test results. Therefore, the fixing mechanism 2 includes a vacuum stage 21 mounted on the frame 1, configured to support and fix the mobile phone back panel 100. In this embodiment, two vacuum stages 21 are provided: one for holding the front-facing mobile phone back panel 100, and the other for holding the back-facing mobile phone back panel 100.

[0062] Understandably, the vacuum stage 21 uses negative pressure adsorption to firmly fix the phone back panel 100 to the stage, effectively preventing the phone back panel 100 from shaking or shifting during the testing process due to external vibrations, displacements, or other factors. This ensures that the phone back panel 100 maintains a precise position and orientation during testing, guaranteeing the accuracy and stability of the testing. Furthermore, the vacuum adsorption force acts evenly on the entire surface of the phone back panel 100 in contact with the stage, ensuring balanced fixation of the phone back panel 100 at all points. This avoids the deformation or damage to the phone back panel 100 that can occur with traditional fixtures due to excessive local pressure.

[0063] It should be noted that the vacuum stage 21 is existing technology. Its structure is relatively simple, mainly composed of a vacuum generator, suction cup, pipes and other components. It has low maintenance costs and is easy to operate, which can effectively reduce the maintenance workload and downtime of the equipment.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
